The cost price of cow = Rs.80
Explanation:
<h2><u>☼︎</u><u>Given :-</u></h2>
- By selling a cow for Rs 144, there is a profit of the same percentage as its cost price.
<h2><u>☼︎</u><u>T</u><u>o Find</u><u>:</u><u>-</u></h2>
<h2 /><h2 /><h2><u>☼︎</u><u>L</u><u>e</u><u>t</u><u>:</u><u>-</u></h2>
- The cost price of cow = Rs.x
<h2><u>☼︎</u><u>Solution :-</u></h2>
<h2><u>Hence: </u></h2>
The cost price of cow =<u>R</u><u>s</u><u>8</u><u>0</u>

Answer:
The term 2lw is independent of the height
Step-by-step explanation:
This formula is usually obtained reasoning like this: the rectangular prism has 6 faces, thus the surface area is the sum of the areas of these faces.
2 faces are l×w rectangles, so their area is lw+lw=2lw. Note that we are not using the height to compute the area, then this is the independent term.
The 4 remaining rectangles involve the height as one of their dimensions, so their areas (2hw+2lh) depend on the height.
Let's use the equation 5x - 20 = 10 as an example for this.
To work backwards from this, you would add the same amount to each side.
You want to isolate the 5x so that you can solve for x.
To do that, you would add 20.
But again, you must add and subtract the same amount to both sides.
So it would look a bit like this:
5x - 20 + 20 = 10 + 20
That would simplify to 5x = 30, or in other words, x = 6.
Basically, you isolate the multiple of the variable then divide the answer to the equation from that multiple.
In the example, 5 is the multiple and after isolating it, the answer was 30.
30 ÷ 5 = 6
x = 6
Hope this helps :)
It is always difficult to map the English description of a mathematical expression to the intended actual expression. The best descriptions are those of 1, 2, 3, 5. Descriptions 4 and 6 are apparently intentionally misleading or absurd.
It appears the appropriate selections are ...
1, 2, 3, 5
